To fill the huge performance gap between the GTX 650 Ti and the GTX 660 and also to compete with AMDs new Radeon HD 7790, nVidia released the GTX 650 Ti Boost. Behind this strange name there`s a GTX 660 hiding whereas one SMX unit has been disabled. Therefore this graphics card is powered by a GK106 with 768 Cuda cores working at 980 MHz with a typical boost of 1`033 MHz. Regarding the memory we have 2 GB of GDDR5 working at 1`500 MHz on a 192 Bit bus. Performance wise the GTX 650 Ti Boost is also a direct competitor of AMD`s Radeon HD 7850."
